AlBr3-mediated multicomponent 1,3-bifunctionalization of donor–acceptor cyclopropanes using arenes and nitrosoarenes as coupling partners is presented. In the cascade, a C–C, a C–N, and a C–Br bond is formed. Reactions are easy to conduct and proceed under mild conditions. The γ,γ-disubstituted N-arylated α-amino esters obtained as products are readily further chemically modified rendering the method
介绍了使用芳烃和亚硝基芳烃作为偶联伙伴的AlBr 3介导的供体-受体环丙烷的多组分1,3-双官能化。在级联反应中,形成一个C–C,一个C–N和一个C–Br键。反应易于进行,并在温和的条件下进行。作为产物获得的γ,γ-二取代N-芳基化α-氨基酯很容易进一步化学修饰,使该方法有价值。
